Be itknown that l, HOWARD M. BARBER, a citizen of the United States, andresident of Stonington, in the "county of New London and StateofConnecticut, have invented anew and nsefulQImpiroWmnt inysheete Handlng Machines, ing is a specification My invention relates to improvementsin signature stitching and folding mechanisms whereby accurate fold ngof the signature along its stitched line is insured by means,

for adjusting. the parts while mechae nisms arefoperatin'g. V

My invention more particularly includes a rotary sheet carrier such, forinstance as the cylinder forming partof a folding mechanism, grippers onthe" carrier, {means for operating thegrippers' at their taking andreleasing points, a st tcher mechanlsm,

its'table, a sheet stop forfthe stitcher table,

acam on the rotary sheet carrier arranged tooperate', the 'sheet stop,to permit the stitched signature to [be taken by the gripperson therotary carrier attheproperitime,

and means. for adj Listing the position of they sheet stop withrs'pectytoithejtakingfpoi it ofsaid grippers whereby the grippers willbe caused to close onto the signature at varying distances from the,head of the signature inthe rotary movement ofthe, carrier toaccuratelyustfthe fold lineto bring it along the stitched line ofthesignature, theWhole. being accomplished while the machine; is. in

operation; it being understood that i the stitcher mechanismfis adjustedtogether with a the sheet stop to maintain; the predetermined distancebetween the sheet stop and the stitched line.

A practical embodiment of my invention is represented in theaccompanying drawings in which- Figure 1 represents in end elevation somuch of a sheet handling machine as will give a clear understanding ofmy invention, the female folding cylinder. being removed.

Fig. 2 is a section taken in the plane of the line Ill-II of Fig. 1, aportion of the female folding cylinder being shown.

Fig. 3 is a detail section at the sheet stop.

The stitcher table is denoted by 'l, the stitcher mechanismgenerally, by2, andits driving shaft; by 8, which stitcher maybe 1 of any well knownor approved construction adapted to stitch a signature While the movement of the signature is arrested on the stitchertable. 'The signaturemay be fed onto'the stitchertable by the endless tape carriers 4:, 5. i

Ihe sheet stop for the stitcher table comprises a plural ty of fingers.6 fixed to a cross the cross shaft '10 supported in the side--framesll, l2 ofthe machine.- The free ends s. ofthese. stop fingers 6,whenthestop is lowered, are located in the. circumferentialj l grooves13.of the rotary sheetcarrier 1-1, which, in the present instance, is onemember of a 'pairof ,coacting {folding cylinders,

the folding cylindersa This rotary carrier 14; is mounted on {asuitablecross shaft 18,

and it carries a set oftnmbler actuated grip-1 perslf), thetumbler 2001:which grippers is engaged by its actuating pin 21 at the taking pointfor the grippers and by the .actu: i

ating pin22 at the. releasing pointfor the grippers, this mechanismbeing known and, approved form.

'tion of the foldingblade15 and folding jaws 16, is not shownherein,butiitis understood. that it may be of any Well known or approvedconstruction operative to cause the signature to be folded off from thecarrier 14 onto the carrier 17. The rotary carrier 14 is provided with aperipheral cam 23 arranged in position to engage a stud or roller 24carried by a two-armed lever 25, 26, fixed of well i t v s5 Themechanism forcOhtrolling the opera-e i to the cross bar 7 of the sheetstop, at the proper time to raise the sheet stop to permit the stitchedsignature to be transferred from the stitcher table 1 to the grippers19. 'A rod 27 is attached at one end to the arm 26,

and slidably engages a stud 28. A spring 29 interposed between this stud28and a collar 30, tends to yieldingly hold thestop in its operativeposition with the fingers 6 in the.

circumferential grooves .13 of the carrier 14. The means which I providefor adjusting the'fold line'with respect to the stitched line anism, 7

This shaft 35 is provided with a] suitable hand wheel38, and'by turningthis hand wheel, the auxiliary frame is moved longitudinallyofthe'table 1. The sheet stop is moved with the auxiliary frame of "theaccomplished by providing upright shafts 39 whichhave a bevelgearengagement 40, 4:1,with the shaft 35, and a bevel gear eni gagement 4:2,43, with the longitudinally arranged shafts 44 mounted adjacent :to thecarriers 43 in fixed bearings 45 and at their other'ends having a screwthreaded engage- 'ment with-studs46 at the 'free'endsfof the de ending"arm-s 8,9.

V It is evidentthat various changes-may be resortedto inthe form, construction andarrangement-of the several parts without de parting'from the spirit andscope of my invention, and hence Ido not wish to limit myself to theconstruction herein shown and described, but
